(Cl. ,2iZv-555) Claims. 1

This invention relates to new and useful im provements in sanitary adhesive tape dispensers.

At the present time adhesive tape is generally sold on metal spools which snap into place in a casing formedof an annular member of sheet metal having an external rolled edge along one side and an internal rolled edge along the other side. Said vannular member is formed with several inwardly pressed tits behind which one of the flanges of the spool engages when itis forced into said casing. The vtape is used by snapping the spool out of the casing, putting the casing down, pulling off a desired length of adhesive tape, and then with a knife or a pair of scissors cutting off the selected length of tape. The casing is then lifted up and the spool is re-engaged into it.

This invention proposes the construction of a new dispenser from which a. length of adhesive tape may easily be drawn and then torn off in an especially simple way without `requiring the use of scissors, knife, or other cutting implement to sever the tape. With the new construction there with be no need to go through the process explained in the previous paragraph of separating the spool of tape from casing, placing the casing on an object, drawing a length of tape off the spool. cutting the tape with scissors, knife or other implement, and then reassembling the spool in the casing. y

In accordance with this invention the new dispenser in characterized by a casing formed of several sections and adapted to fully enclose a. roll of tape, and having an open portion through which the end portion of the tape may pass. One Aof said casing sections is `provided with'a point located in the vicinity of the open portion and having sharp tape tearing edges over which said tape may be torn. 'It is also contemplated that one of said sections -of said casing.

should be movable and in one position of said movable section said tape shall be clamped against said point by engaging 'between sections of said casing to facilitate tearing olf ofthe tape against the point. The parts are also arranged so that in another position of the movable casing section the tornend of the remaining tape is free from v.being clamped by lsaid casing sections and may be gripped and pulled for drawing out as much additional tape as needed. After a `desired quantity of tape has been draw-n out, the movable casing section may be returned to its first position in which the new drawn piece of tape may be torn off.

The broad principals of the new dispenser as characterized in the previous paragraphs may be embodied in various forms of dispensers, either portable or for stationary attachment to supports. In this following specification two forms have been disclosed and described. In one of these forms the movable section is hingedly mounted in order to be movable into .the two positions referred to. In the other form the movable section is rotatively mounted in order to `be moved into the two positions specified.

It is another object of this invention to so con-.- struct the parts of the new dispenser that they may be made 10.0% from a rigid type. of plastic material. This construction is highly desirable in that no metal knives, or other foreign parts are required in the dispenser for facilitating the tearing off of the tape. If desired some of said plastic material may be transparent so that the tape in the dispenser is visible so that the quanf..

tity left is easily seen. Another feature resides in the fact that the new dispenser may be of the same size as present day tape holders.

A still further object of this invention resides in so constructing the parts of the dispenser that they may be merely snapped together into assembled condition.

A further object of the invention is the con. struction of a device as described, which is sim, 111e and durable and which may be manufa tured and sold .at a reasonable oost.

For further ,comprehension of the invention,

and of the objects and advantages thereof,rv..4

The new sanitary adhesive tape dispenser, or dispenser for other types of tapes, ribbons and strips, in accordance with one form of this invention, includes a casing having a main section I0 having an open bottom portion I I formed with a pointed end I2. A cylindrical support I3 for a roll of adhesive tape which is schematically indicated by reference numeral I4, is mounted in said casing I0 in order that the end of said tape I4 may be drawn through said pointed end I2 of said open bottom portion I I (see particularly Fig. l). A base closure casing section I6 is provided for closing said open bottom portion II. This base closure section I6 has a pointed end I'I formed with sharp tape tearing edges I8 normally engaging in said pointed end I2 of said open bottom portion II in order that said tape I4 may be torn off said pointed end I7 of said base closure section I6. Said base closure section I6 is hingedly mounted on the bottom portion II of said main section I0 in order that it may hinge open to make additional tape I4 from said roll I4 accessible to be drawn over said pointed end I1 of said base closure section I6.

The cylindrical support I3 is formed with a central opening 20. This opening 2i) is provided with an inwardly directed key portion 2I by which the support I3 may be readily turned for winding the tape I4 on it. The ends of the support I3 are formed with reduced portions 22 of slightly smaller diameter than the central portion of the support to form shoulders for turnably holding the support I3 in position in the casing I0. The main casing section III is provided with circular side openings 24 in its side walls into which the reduced ends 22 of the support I3 engage. Each of the side walls of the main section I0 is formed with a top portion above the horizontal center of the openings 24 spaced slightly inwards of a bottom portion 26 below the horizontal center of the openings 24 in order that the section I0 may easily be formed from rigid type plastic material with a simple mold which opens up and down. By 01T- setting the portions 25 and 26 of each of the side walls of the section I as illustrated in Fig. 2 it is possible to mold the openings 24 in said side walls with a simple separation die. The support I3 is slightly wider than the distance between the bottom portions 26 of the side walls of the section I0 so that the support I3 may easily be engaged in position by ilexing the bottom portions 26 of the section I0 apart while forcing the support I3 upwards from the bottom until it snaps into position in the openings 24.

The main section I0 is molded with side flanges 30 at one end portion of the said open bottom portion II of said casing. Openings 3| extend upwards through said flanges 30 and into the bottom portions 26 of the side walls of the section I0, see Fig. 5. The base closure section I6 is provided with a pintle rod portion 32 which normally engages through said openings 3| and which rests upon said side flanges 30 and by which the base closure section I6 is' hingedly mounted upon the bottom portion of the casing I6. The dot and dash lines I6 in Fig. 1 indicate a pivoted position of the base closure section I6 using the pintle rod portion 32 as a pivot. The ends of said pintle rod portion 32 are formed with beveled portions 34 for facilitating engaging the ends of said pintle rod portion 32 into said openings 3I and upon said flanges 30. The bevels 34 diverge from the back to the front when the base closure section I6 is held in a horizontal position as illustrated by the full lines on the drawing. The base closure section I6 may be snapped into position, by first holding it in a vertical lposition at right angles to the bottom of the casing I0 so that the narrow portion between the beveled ends 34 of the pintle rod portion 32 may be engaged into the bottom portions of the openings 3I between the fianges 30. Then the base closure section I6 is forced upwards so that the beveled portions 34 ex the side portions of the main section I0 slightly until they reach positions above the top faces of the iianges 36. Now the base closure section I6 is free to pivot into a closed position.

The base closure section I6 is provided with projecting side portions 35 in the nature 0f side iianges. The left hand ends of these flanges are formed with beveled portions 36 which mate with complementary beveled ends on the flanges 30.

These projecting side flanges 35 have their rightl hand ends provided with enlarged portions 31 which act as handle portions which may easily be gripped and by which the base closure section I6 may be pivoted open and closed.

The base closure section I6 is provided with a tail portion 38 to the left of the pintle pin portion 32 which normally engages into a portion of the open bottom I I of the main section I0 for closing same. The base closure section I6 has a portion to the right of the pintle pin portion 32 which extends into the open bottom II of the main section I0. This latter portion is formed with beveled sides 40 for insuring a better closed position for the base closure section I6. The base closure section I6 preferably is molded in one piece from rigid type thermoplastic material.

The operation and use of this new adhesive tape dispenser may be understood from the following:

The end of the tape I4 extends down between the pointed end II of the base closure section I6 and the pointed end portion I2 of the open bottom portion II. The base closure section I6 may be pivoted downwards by pushing against the portions 31, to reach a position as illustrated by the dot and dash lines I6'. tape I4 will be projecting from the bottom of the main casing section IIJ and may be manually gripped and pulled olf of the pointed end I'I olf. the base closure I6 to which it normally adheres. Any length of tape I4 may now be drawn out and then the base closure section I6 may be pivoted back to its original position into the open bottom portion I I of the main casing section I 0. The projecting portion of the tape I4 may be torn off by holding the base closure section I6 closed and pulling the tape down against the pointed portion I'I of the base closure section I6. The operation may be repeated for removing additional lengths of tape I4.

Particular attention is called to the fact thatA lengths of tape I4 may be removed from the dis,

penser without requiring the use of a pair of scissors or a knife. Moreover, there is no need to separate the casing from the roll of tape, as

Now a portion of the is now -generallydone. The new dispenser is made from three parts, namely, the casing main section I0, the support |3, and the base closure section I6. These parts hold the tape |4 as well as providing means by which lengths of tape may be torn off.

The new dispenser may be constructed of transparent rigid type plastic material so as to act as a display case for the tape therein.

In Figs. 6-11 inclusive another form of this invention has been disclosed. This dispenser includes a casing formed of several sections, namely, two sections, indicated by reference numerals 40 and 4|. This casing is adapted to fully enclose a roll of tape. Said casing also is pro videdwith an open portion 42 through which the end portion of said tape may pass. A point 43 is formed on one of said sections, namely, the section 40, and is located in the vicinity of said open portion 42. This point 43 has sharp tape tearing side edges over which the tape may be torn ofi. One of the sections of said casing, namely, the section 4|, is movable and in one position of said movable section, the position illustrated in Fig. 6, said tape will be clamped against said point 43 by engaging between the sections 40 and 4| tol facilitate tearing of said tape against said point 43. Said movable section 4| is movable to another position, the position shown in Fig. 11, in which the torn end of the remaining tape will be free from being clamped by the sections 40 and 4|, and may be pulled for pulling out additional tape from the casing as required.

The casing section 40 has a disc wall 44 and a skirt wall 45 extending along the edges of said disc wall 44. Said skirt wall 45 is formed with said open portion 42. One end of this open portion 42 is formed with said point 43, and the other end 46 of the opening 42 is merely straight. The casing section 4| includes a disc wall 41 for extending across the skirt wall 45 for closing the casing. The section 4| also has a short skirt wall 48 for extending across the open portion 42 of sai-d casing section 40 for closing said open portion 42. The short skirt wall 48 fits inside of the skirt wall 45 as may be particularly seen from an inspection of Fig. '1.

The casing section 4| is turnably connected with the casing section 40 by several inwardly directed lugs 49 from the skirt wall 45 behind which the disc wall 41 of the casing section 4| engages. The short skirt wall 48 is formed with a slot through which the end of tape from within the casing may pass in order that the end portion of the tape passes through said open portion 42. Means is provided for limiting turning of the casing sections relative to each other so that the casing section 4| may be turned to one position in which said slot 5|! is beneath said point 43, as illustrated in Fig. 6, to clamp said tape against said point 43 to facilitate tearing off said tape against the point 43. The casing section 4| may be turned to a second position in which the slot 53 is free of the point 43 and located within the open portion 42, as illustrated in Fig. 1l, in order to free the torn end of the remaining tape so that it may be gripped and additional tape pulled out of the casing.

A cylindrical support 5| is `formed on one of said casing sections upon which the roll of tape may be engaged. More particularly, the cylindrical support 5| is formed on the casing Isection 43. This cylindrical support 5| is provided with a central opening 52. The free end of the cylindrical support 5| is provided with a reduced diameter section 53 Vforming a back shoulder 5.4. The disc Wall 41 is provided with an opening 55 engaging upon this reduced diameter portion 53. The disc wall 41 also rests against the back shoulder 54. This construction assists insupporting the disc wall 41 and holding it spaced from the disc Wall 44.

The short skirt wall 48 is provided with a projecting lug 56 which may be used as a handle for turning the casing section 4 The means for limiting turning of the casing section 4| to the two positions referred to previously, includes the lug 56 which acts as a limiting projection. When the casing section 4| is turned clockwise, in relation to Fig. 7, the lug 56 will strike the end 45 of the opening 42, as illustrated in Fig. 11. This limits turning of the casing section 4| in this direction. The inner face of the skirts wall 45 i-s formed with a projection 58 against which the end 59 of the short skirt wall 48 may strike to limit turning of the casing section 4| in a. counter-clockwise direction in relation to Fig. 7.

The short skirt wall 4B to the left of the lug 53 extends slightly inwards of the periphery of the disc wall 41 forming a space 60, see Fig. 10, to accommodate the thickness of the tape as the tape passes from within the casing, then through slot 50 and over the short skirt wall 48 and beneath the point 43.

The operation of this form of the dev-ice may be understood from the following:

While the casing sections 4|] and 4| are in a separated position, a roll of tape is placed on the cylindrical support 5|. Said casing sections are then placed together with the end of the roll of tape engaging up through the slot 50 and over the short skirt wall 48 and through the opening 42. The casing section 4| is now forced inwards upon the casing section 40 so that the disc wall 41 snaps behind the lugs 49.

A length of tape may be removed from the dispenser as follows: The casing section 4| is turned clockwise by moving the lug 53 against the shoulder 46, as shown in Fig. l1. Now the end of the tape extending through the slot 50 is accessible. It may be gripped and any length of tape pulled from the roll of tape in the casing. The casing section 4| is now turned back to the position shown in Fig. 6 so that the projecting tape is clamped between the point 43 and the short skirt wall 48 of the casing section 4|. 'gie tape now may be torn off against the `point While I have illustrated and described the preferred embodiments of my invention, it is to be understood that I do not limit myself to the precise constructions herein disclosed and the right is reserved to all changes and modications coming within the scope of the invention as dened in the appended claims.

I- Iaving thus described my invention, what I claim as new and desire to secure by United States Letters Patent is:
